Flashing Bios

I softmod my Xbox this week using Splinter Cell Hack (idiot tools package)... i installed X2 Bios recommended on the Idiot Tools package ... now can i change my bios ? if yes, which one you suggest me ? and it is possible to put more than 1 bios on the Box ?

This post should be in the gamesave/xbe exploit forum, not TSOP flashing. If all you did was softmod it, it belongs there. Replace the bios accordingly if you are using PBL or some other variation of it.
